Abstract
"PROCESSO PARA A RECUPERAçãO DE ZINCO METáLICO DE UM MINERAL DE ZINCO, MéTODOS PARA A REMOçãO DE MANGANêS DE UMA SOLUçãO DE HALETO METáLICO, E PARA REMOçãO DE PRATA E/OU MERCúRIO DISSOLVIDOS DE UMA SOLUçãO DE HALETO METáLICO, E, QUALQUER METAL". Um processo para a recuperação do zinco metálico de um mineral de zinco inclui as etapas de lixiviação do mineral de zinco em uma solução que inclua uma espécie de haleto formada de dois ou mais haletos diferentes, para lixiviar o zinco na solução. A solução que carrega o zinco é então eletrolisado para produzir o zinco metálico e para gerar a espécie de haleto. A solução eletrolisada que inclui a espécie de haleto retorna então à etapa de lixiviação. Uma porção da solução eletrolisada pode ser removida como uma corrente de drenagem de um compartimento do cátodo de uma célula eletrolítica do processo de eletrólise e processada para remover manganês como precipitado de dióxido de manganes mediante adição a ela de pedra calcária, e da espécie de haleto de um compartimento do ânodo do processo de eletrólise. A este respeito, o pH e o Eh da solução podem ser regulados de uma maneira que favoreça a formação do precipitado de dióxido de manganês durante a formação de um precipitado de zinco."PROCESS FOR RECOVERY OF METAL ZINC FROM A ZINC MINERAL, METHODS FOR REMOVAL OF MANGANES FROM A METAL HALIDE SOLUTION, AND FOR REMOVAL OF SILVER AND / OR MERCURY SOLUTION", METALLIC METAL HALIDE SOLUTION A process for the recovery of metallic zinc from a zinc mineral includes the zinc mineral leaching steps in a solution that includes a halide species formed of two or more different halides to leach zinc in the solution. The zinc-bearing solution is then electrolyzed to produce the metallic zinc and to generate the halide species. The electrolyzed solution that includes the halide species then returns to the leaching step. A portion of the electrolyzed solution may be removed as a drainage stream from a cathode compartment of an electrolytic cell from the electrolysis process and processed to remove manganese as a manganese dioxide precipitate by addition of limestone, and halide species. anode compartment of the electrolysis process. In this regard, the pH and Eh of the solution may be regulated in a manner that favors the formation of the manganese dioxide precipitate during the formation of a zinc precipitate.
